I am currently struggling with the explanation of how we use the word "much" My students understand the countable and uncountable part quite well, the problem is they can't grasp the habit of modifiers such as: too, as, very, so, etc..Examples: "...books can give me much knowledge." OR "....can earn me much money."

I tell them that we must use these modifiers-so,too,very- to explain 'how much' when stative and use-as- to explain as a comparitive.Of course their next question is, "Why?"

How can I explain when we use "a lot of/lots of" to easily replace "much" and why we add the modifiers mentioned above?
